Anthropic is set to spend about $45 billion to rent artificial intelligence computing capacity from cloud infrastructure provider Nscale, according to a person familiar with the agreement.

The six-year deal will give Anthropic access to roughly 460 megawatts of capacity at Nscale’s data center campus in West Virginia, supporting the company’s rapidly growing demand for AI training and inference.

Nscale is expected to deploy Nvidia’s next-generation Vera Rubin chips for the project, giving Anthropic access to some of the latest hardware designed for large-scale AI workloads.

The agreement comes as Anthropic prepares for a major public listing and continues to increase spending on GPUs, data centers, model development and hiring. Demand for products such as Claude Code has pushed the company to secure significantly more compute capacity.

Anthropic has also struck major infrastructure agreements with other technology suppliers. AMD previously announced plans to sell the company tens of billions of dollars in AI servers while investing up to $5 billion in Anthropic.

The Claude developer is projecting revenue of roughly $190 billion to $200 billion by 2028, compared with a current annualized revenue run rate of about $47 billion.

The Nscale deal underscores the enormous capital requirements facing leading AI companies as they compete to secure enough computing power for increasingly sophisticated models and rapidly expanding customer demand.
